----------------------------------
Summary: Could the partial score sum from essential list scores be cached?
Key: LUCENE-10636
URL: https://issues.apache.org/jira/browse/LUCENE-10636
Project: Lucene - Core
Issue Type: Improvement
Reporter: Zach Chen
This is a follow-up issue from discussion [https://github.com/apache/lucene/pull/972#discussion_r909300200] . Currently in the implementation of BlockMaxMaxscoreScorer, there's duplicated computation of summing up scores from essential list scorers. We would like to see if this duplicated computation can be cached without introducing much overhead or data structure that might out-weight the benefit of caching.
